without isohybrid it never worked for me (I tested several USB sticks,
two gislab images). The manual says

"""
The  isohybrid  utility  modifies  an  ISO  9660  image  generated with
       mkisofs, genisoimage, or compatible utilities, to be bootable as a  CD-
       ROM or as a hard disk.
"""

Probably something related to genisoimage/mkisofs parameters [1]?

Sorry, not having better insights.

Martin
